Nonindigenous Aquatic Species (NAS) Database Non-freshwater Specimens

This dataset contains the non-freshwater specimens from the Nonindigenous Aquatic Species (NAS) database, which was established as a central repository for spatially referenced biogeographic accounts of introduced aquatic species. The NAS program provides scientific reports, online/real-time queries, spatial data sets, regional contact lists, and general information. The data is made available for use by biologists, interagency groups, and the general public. The geographical coverage is the United States.本数据集包含来自外来水生物种数据库（Nonindigenous Aquatic Species, NAS）的非淡水标本。该数据库作为收录外来水生生物空间参考生物地理记录的中央资源库而设立。外来水生物种项目可提供科学报告、在线/实时查询服务、空间数据集、区域联络清单及通用资讯。本数据集面向生物学家、跨机构团队与普通公众开放使用，其地理覆盖范围为美国全境。
